Today, solar panels come in many varieties to meet the different cost, performance, size, efficiency, and aesthetics needs of customers.
- THIN FILM
Considered “premium,” high efficiency, requires less roof space, usually black colored
- MONO-CRYSTALLINE SILICON
Cheaper, low-moderate efficiency, could be flexible, lower temperature degradation.
- POLY-CRYSTALLINE SILICON
Cheaper, moderate efficiency, usually blue colored
Putting Solar Panels Together
Solar cells made from these technologies are connected together, usually in sets of 60, 72, or 96 cells to form a solar panel, or module. The panel, or modules, in turn, are connected together to form arrays (e.g. groupings on different roofs), which are then collectively referred to as the Solar System.
Example: Panasonic N330 (VBHN330SA16) panel is composed of 96 N-Type, Mono-crystalline cells.
